bj Loch Scaslavat. The area is about 172 acres, and the volume 260 
millions of cubic feet. It receives only local drainage from an area of 
scarcely 1 mile square, and discharges northward by the Amhuinn 
Benisval, a quarter of a mile long, into Loch Cro Criosdaig. The height 
above sea-level was 278*0 feet on August 3, 1903.

Loch Bodavat (see Plate LXXXIX.) is a small loch to the north of 
Loch Resort, into which it drains by a stream about a mile long. The 
hills to the north-west rise some 300 feet, those on the south-east 200 
feet, above the loch. In form it is narrow, with a sigmoid curvature, and 
measures nearly a mile from north-east to south-west in a straight line 
between the ends. The greatest breadth near the centre is a quarter of a 
mile. The basin is simple, deepest in the middle, with the maximum of 
46 feet a little east of the centre. The mean depth is 13 feet, the area 
about 91 acres, and the volume 50 millions of cubic feet. It receives the 
drainage of an area of Ij square miles. The outflow is from the south-west 
corner of the loch. The surface was 179*6 feet above sea-level on August 
1, 1903. 
The range of temperature from surface to bottom was 5° Fahr.

From the following table it will be seen that in the thirty lochs under 
consideration 2896 soundings were taken, and that the aggregate area 
of the water-surface is 9| square miles, so that the average number of 
soundings per square mile of surface is 300. The aggregate volume of 
water contained in the lochs is estimated at 7409 millions of cubic feet. 
The area drained by these lochs is 152 square miles, or nearly sixteen 
times the area of the lochs.
